SP Performance Cross-Drilled and Slotted Brake Rotors are a unique design offering the best combination of cooling and out-gassing. In fact, our design is so unique we would like to go over some of the details. The first thing we will point out on the drilled rotor is the chamfer. Unlike our competition there is no edge on our chamfer. This is accomplished by the use of an outer radius curve rather than a countersink. With the radius curve, or Sinusoid Curve", it virtually eliminates an edge on the surface of the hole. With no edge, there is less stress build up, thus reducing the chance of surface checking. This smooth surface also makes the rotor more pad friendly by reducing the wear of the pad caused by the friction scraping against a sharp edge

Available in these options:SP Performance Drilled and Slotted Brake Rotors With Standard Gray ZRC Finish:All rotors are provided with our gray ZRC coating. It provides long-lasting protection against corrosion in the most hostile salt-water environments. After being applied, ZRC provides the highest level of galvanic protection. The film of ZRC is conductive. After the coating heats up during use, it bonds permanently to the metal surface. It will not allow the metal to corrode, even when the surface is scratched

SP Performance Drilled and Slotted Brake Rotors With Optional Bright Silver Plating: Electro- plating is performed on our rotors to provide a brighter finish which is more appealing to the look of the rotor. When plating a rotor, a metallurgical bond is formed between the plating and steel, forming an iron rich alloy with tenacious bond where it will form its own protective oxide layer. Electro- plating is very effective in combating the corrosion of the rotor.
